This week, Jimmy Fallon interviewed "Michael Jordan" (a.k.a. Kristen Wiig masquerading as the basketball legend), and a young woman re-recorded Alanis Morissette's song "Ironic," changing the lyrics so that the events actually were, you know, ironic. Geeks and nerds everywhere geared up for Comic-Con, including Nerdist founder Chris Hardwick, who kicked off his second annual "Course of the Force" relay. And an English photographer celebrated his son's first birthday by posting a video documenting one second of every day of his life. Check out those clips and more in our weekly roundup of the best online videos:

Dad's Touching Baby Video: British photographer Sam Cornwell has filmed his baby son, Indigo, every day of his life since he was born last summer.

How Hot Does It Get In a Car?: This video isn't new, but with the heat wave that's been some areas of the country miserable this week, it's certainly timely. Here, a doctor demonstrates how hot it can get in a car, even if the windows are cracked — and the results are surprising. Lesson: Bring your pets and kids with you!

Course of the Force — For the second year in a row, Nerdist founder Chris Hardwick is kicking off his "Course of the Force" project — an Olympic-style relay race with a light saber — at Comic-Con. Here's the first video in this year's series (via Tubefilter):
